Enum Property

pub enum Property {
    File(PathBuf),

    Stack,
    Huge,
    Anon(usize),
    Dirty(usize),

Properties for memory regions. Consult man 7 numa for details.

Variants

File(PathBuf)

File backing the memory region.

N(usize, usize)

Size on each numa node (numa_node, size). Size in pages, or bytes after normalizing.

Heap

Memory range is used for the heap.

Stack

Memory range is used for the stack.

Huge

Memory range backed by huge pages. Page size differs from other entries.

Anon(usize)

Number of anonymous pages in range.

Dirty(usize)

Number of dirty pages in range.

Mapped(usize)

Number of mapped pages in range.

MapMax(usize)

Number of processes mapping a single page.

SwapCache(usize)

Number of pages that have an associated entry on a swap device.

Active(usize)

Number of pages on the active list.

Writeback(usize)

Number of pages that are currently being written out to disk.

Kernelpagesize(usize)

The size of the pages in this region in bytes.

Implementations

impl Property

pub fn page_size(&self) -> Option<usize>

Returns the kernel page size if the property matches the page size property.

pub fn normalize(self, page_size: usize) -> Option<Self>

Normalize the property given the page size. Returns an optional value, which is set for all but the page size property.

Trait Implementations

impl Debug for Property

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for Property

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Ord for Property

fn cmp(&self, other: &Property) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Property

fn eq(&self, other: &Property) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Property

fn partial_cmp(&self, other: &Property) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
